    I'm running a 235 Chevy with fenton intake, dual carbs, HEI, split headers, etc. Internally, it is freshly rebuilt, but stock. This is a powerglide car.

    Currently I have a pair of rebuilt rochesters on it. They were running very lean, but I have fattened them up and fiddled with them for months. They constantly leak fuel and cause the engine to stumble and pop with hard acceleration from a dead start. They also foul plugs very regularly. Once cruising, they run great.

    I want to swap out the carbs for Carter YF's or possibly some kind of Weber. What carbs are recommended for a dual setup on a mostly stock 235?
     
  2. The YF is a common swap, if you can find the Chevy ones. Less prone to leaking and should even improve milage some.

    Thanks, that's a great link! I used a unisyn to sync the rochestors, but my method was a little different than the one in the link.

    Right now I am leaning towards the Carter/Weber 2bbls from Langdon.

    I am not running manifold heat right now either, so hopefully once I get that plumbed up in will help some as well.
